FD2 again was a relatively short workday for the ISS crew, with wakeup last evening at 6:30pm EDT and back to sleep this morning at 5:00am.

Upon wakeup last night, crewmembers Barratt, Kopra, Thirsk & De Winne continued their current support of the experiment SLEEP (Sleep-Wake Actigraphy & Light Exposure during Spaceflight), logging data from their Actiwatches to the HRF-1 (Human Research Facility 1) laptop as part of a week-long session.

FE-1 Barratt started preparations for the Shuttle docking by performing a joint procedures review of the RPM operations with CDR Padalka & FE-4 Thirsk.

Thirsk recharged five D2X camera batteries during the day for at least three hours. [Three batteries to be used for configuring the cameras in preparation for the RPM documentation, the fourth & fifth kept as backups for the actual RPM.]

Afterwards, Barratt configured the D2X digital cameras with batteries installed (to keep Time/Date setting accurate), while Thirsk set up the BPSMU (Battery Powered Speaker Microphone Unit) at the Lab RWS (Robotic Workstation) using pre-routed cables, and the second BPSMU near the Node-2 forward hatch for placement in the Discovery ODS after docking.

FE-2 Tim Kopra set up the THC IMV (Temperature & Humidity Control/Intermodule Ventilation) in the USOS (US Segment), configuring diffusers in the Lab to optimize air mixing for CO2 removal and installing a temporary (additional) air duct in Node-2 for increased Shuttle ventilation.

The FE-4 hooked up the UOP DCP (Utility Outlet Panel/Display & Control Panel) power bypass cable at the CUP RWS (Cupola Robotic Work Station) for video coverage of the Shuttle approach with the SSRMS (Space Station Remote Manipulator System) cameras.

In preparation for the docking, Mike Barratt supported the ground in pressurizing & leak-checking the PMA-2 (Pressurized Mating Adapter 2) for ingress, hatch opening and stowage after the Shuttle’s arrival. [PMA-2, at the ISS bow, serves as the docking port for Discovery].

Frank De Winne collected water samples from WRM (Water Recovery & Management) condensate and JPM ITCS LTL (Internal Thermal Control System / Low Temperature Loop) for return to Earth on the Shuttle.

In preparation for the 17A spacewalks, Bob Thirsk worked in the US Airlock (A/L) removing panels at OA2 as a get-ahead for O2 transfer setup on FD3. FE-2 Tim Kopra had Day 1 of another session with the CCISS (Cardiovascular & Cerebrovascular Control on Return from ISS) experiment, using the HRF PC1 (Human Research Facility Portable Computer 1. [Tim set up the hardware, then began his 24-hr. on-orbit session with the CCISS experiment (with Bob Thirsk acting as operator and photographer) by donning the HM2 (Holter Monitor 2) and the CBPD (Continuous Blood Pressure Device), performing the Baro Study, and starting the 24-hr passive heart rate data collection. Data were recorded on a PCMCIA memory card, with the HRF (Human Research Facility) rack laptop for control. CCISS studies the effects of long-duration spaceflight on crewmembers' heart functions and their blood vessels that supply the brain (= “cerebrovascular”). Learning more about the changes in cardiovascular & cerebrovascular systems in zero-G could lead to specific countermeasures that might better protect future space travelers. For the Baro study of CCIS, heart rate and blood pressure are being recorded for resting and timed breathing for 5 min, with no caffeine or food (water is acceptable) allowed two hours before the start of the Baro Study and no exercise prior to the Baro Study.]

FD 2 midday meal (“lunch”) was timelined at 11:16pm-12:16am.

In the JAXA “Kibo” JPM, De Winne collected 12 area radiation dosimeters and stowed them for return on 17A.

Afterwards, Frank transferred the exercise data files to the MEC (Medical Equipment Computer) for downlink, including the daily wristband HRM (Heart Rate Monitor) data of the workouts on ARED, followed by their erasure on the HRM storage medium (done six times a week).

After beginning their sleeptime at ~5:00am this morning, the crew woke up to FD3 (Flight Day 3) today at 1:30pm EDT.Flight Day 3:

Upon wakeup, Barratt, Kopra, Thirsk & De Winne continued their current support of the experiment SLEEP (Sleep-Wake Actigraphy & Light Exposure during Spaceflight), logging data from their Actiwatches to the HRF-1 (Human Research Facility 1) laptop as part of a week-long session.

Frank De Winne performed the periodic WPA (Water Processor Assembly) sample analysis in the TOCA, after first priming (filling) the TOCA water sample hose. After the approximately 2 hr TOCA analysis, results were transferred to SSC-7 (Station Support Computer 7) via USB drive for downlink, and the data were also logged for calldown. [The current procedure is a work-around for TOCA’s failed catalyst.]

Frank also took surface samples in the JPM using MDS (Microbial Detection Sheets) spread out at specific sampling locations (Saibo Rack wall, Node-2/JEM hatch handrail, JPM OA1 diffuser) with cover film open. After taking documentary photography, the sampling sheets were packed for return.

The CDR did the daily IMS (Inventory Management Sytstem) maintenance, updating/editing its standard “delta file” including stowage locations, for the regular weekly automated export/import to its three databases on the ground (Houston, Moscow, Baikonur).

Padalka also performed the routine daily servicing of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM (Service Module), including the weekly collection of the toilet flush (SP) counter and water supply (SVO) readings for calldown to TsUP-Moscow. Today’s servicing included the weekly Check-up on the Russian POTOK-150MK (150 micron) air filter unit of the SM’s SOGS air revitalization subsystem, gathering weekly data on total operating time & “On” durations for reporting to TsUP-Moscow. [Regular daily SOZh maintenance consists, among else, of checking the ASU toilet facilities, replacement of the KTO & KBO solid waste containers and replacement of EDV-SV waste water and EDV-U urine containers.]

FD3 midday meal (“lunch”) for the ISS crew was set for tonight at ~6:55pm-7:55pm.

As part of final preparations for STS-128/Discovery arrival, FE-4 Thirsk verified closure of the Lab & Kibo JPM science window shutters as protection against thruster plumes. [The window shutters must remain closed when Shuttle is within 3000 ft/915m of the ISS. They may be opened for no more than 15 minutes for photo documentation if the Shuttle is in Freedrift.]

Kopra checking the proper hook-up of the UOP DCP (Utility Outlet Panel/Display & Control Panel) power bypass cable at the CUP RWS (Cupola Robotic Work Station) for video coverage of the Shuttle’s approach & docking with the SSRMS (Space Station Remote Manipulator System) cameras, then also

Thirsk configuring & later activating the camera timers upon Orbiter RPM initiation and handling the camcorder (the timers indicated beginning & end of the bottom-side photography window),

The CDR performing final STTS communications configuration checks for the docking; then

Configuring proper headset connection for supporting the RPM activity (which resulted in several hundred pictures of the Orbiter bottom TPS), and

Verifying powerdown of the amateur radio equipment in the SM to prevent RF interference during the proximity & docking ops.

During the RPM photography session (8:05pm-8:20pm), Gennady wielded the 400mm-lens D2X camera (replacing the earlier DCS-760), Mike the 800mm-lens D2X for documenting the tile acreage & bottom-side door seals). [The RPM was used by the crew for the bottom-side mapping of the Orbiter at the arrival of the Shuttle. During the RPM at ~600 ft from the station, Mike & Gennady, the “shooters”, had only ~90 seconds (out of the total 9 min of imaging) for taking high-resolution digital photographs of all tile areas and door seals on Endeavour, which Mike prepared for downlinked after completion of the “shoot” at ~4:20pm for launch damage assessment. Thus, time available for the shooting was very limited, requiring great coordination between the two headset-equipped photographers and the Shuttle pilot.]

During the Shuttle approach & docking preparations, Roman Romanenko used the Russian video camcorder for filming another “Life aboard ISS” video intended for public airing by the Russian Vesti 24 TV news channel in their “Kosmos” segment.

At ~8:30pm, Mike Barratt downlinked the RPM imagery from three SSC (Station Support Computer) laptops.

Shortly before the docking, the crew configured the Russian MCS (Motion Control System) for the automatic “PMA-2 Arrival” mode, an operational sequence used to monitor Orbiter arrival at the PMA-2 (Pressurized Mating Adapter 2). [Handover of attitude control authority to the Russian MCS took place at 7:18pm. At “Capture Confirmed” (8:54pm), ISS attitude was immediately set to Freedrift for about 25 min. to allow dampening out relative motions of ISS with the ODS (Orbiter Docking System) dampers/shock absorbers, then maneuvered to “Mated TEA” (Torque Equilibrium Attitude) to account for the new overall configuration with Discovery-docked. Control authority will be returned to US CMG (Control Moment Gyro) momentum management at 10:37pm.]

The docking was followed by leak checks of the ODS (Orbiter Docking System) vestibule for about half an hour.

After a final checkout/verification of IP-1 airflow sensors and their ventilation performance in the various RS hatchways by Romanenko, ISS/STS hatches will be opened at approximately 11:00pm, followed by the traditional Crew Welcome Ceremony and the mandatory 25-min. Safety Briefing for the new arrivals at ~11:10pm. [The station now has 13 inhabitants again.]

Upon hatch opening, before installation of the ventilation airduct between ISS and Discovery, the FE-3 will perform the standard collection of air samples with the Russian AK-1M sampler in the SM, FGB, Lab, and then also in the Orbiter.

Next, FE-2-20 Nicole Stott & CDR Padalka will transfer Stott’s IELK (Individual Equipment Liner Kit) seat liner from the Shuttle to the Soyuz TMA-14/18S crew return vehicle where Padalka installs it for the new FE-2 (~1:44am). Tim Kopra’s IELK seat liner will be pulled out and stowed in the Shuttle for return to Earth. [A crewmember is not considered transferred until his/her IELK, AMP (ambulatory medical pack) and ALSP (advanced life support pack) drug kit are transferred. After today's reconfiguration of the FE-2 IELKs, Timothy will have technically become a member of the Discovery crew aboard ISS, and Nicole a crewmember of the space station.]

Also in the Soyuz TMA-14, Gennady Padalka will –

Conduct the standard leak check on Stott’s Sokol in-cabin spacesuit (in case it is required for her return on the Soyuz), and

Afterwards, Bob transferred the exercise data files to the MEC for downlink, including the daily wristband HRM (Heart Rate Monitor) data of the workouts on ARED, followed by their erasure on the HRM storage medium (done six times a week).

Crew sleep aboard the ISS will commence at 5:00am tomorrow morning, aboard the Discovery at 5:30am.

No CEO photo targets uplinked for today.

CEO photography can be studied at this “Gateway” website:http://eol.jsc.nasa.gov (as of 9/1/08, this database contained 770,668 views of the Earth from space, with 324,812 from the ISS alone).

ISS Crew Sleep Shifting: To synchronize the ISS crew’s timeline with STS-128/17A arrival and docked activities, the station’s wake/sleep cycle is undergoing a number of shifts starting on 8/29. For the next few days, the schedule is as follows:
